摘要
本文介绍了泵内汽蚀的发生机理,重点介绍了泵系统的有效汽蚀余量、必需汽蚀余量、允许汽蚀余量以及允许吸上真空高度和允许倒灌真空高度的概念,并且从泵的制造、运行和用户的角度分析了防汽蚀的措施。
Inside the pump cavitation were introduced in this paper, the mechanism ofpump system is mainly introduced the effective NPSH, necessary NPSH, NPSH, and allowthe vacuum suction height and allowed to flow backward concept of high vacuum, and fromthe Angle of the pump manufacture, operation and user analysis the measures to preventcavitation.
